WlNDO'W-SCREEN.

SPECIFICATION forming part of Letters Patent No. 355,340, dated January4, 1887.

Application filed July 2, 1886.

To (ZZZ whom it may concern:

' Be it known that I, JAMES L. RoeERs, of Marshfield, in the county ofPlymouth, State of Massachusetts, have invented a certain new and usefulImprovement in Window-Screens, of which the following is a descriptionsufficiently full, clear, and exact to enable any person skilled in theart or science to which said invention appertainsto make and use thesame, reference being had to theaccompanying drawings, forming part ofthis specification, in

whieh- Figure 1 is a front elevation of my improved window-screenrepresented as in use, and Fig. 2 a vertical longitudinal section of thesame.

Like letters of reference indicate corresponding parts in the differentfigures of the draw ings.

My invention relates to that class of window-screens which are designedfor excluding flies, dust, &c.; and it consists in a novel constructionand arrangement of parts, as hereinafter more fully setforth andclaimed, the object being to produce a more effective and otherwisedesirable article of this character than of which may be of the ordinaryform and construction. Secured to either side of the frame by the screwsa: there is a vertically-arranged strip, D, said strips being providedon their contiguous edges with grooves m, which form ways or runs forthe screen. A horizontally-arranged cross-bar, E, is fitted tightly intothe top of the frame in front of the ways for the lower sash, andjournaled horizontally in front of said bar there is an ordinary springshade-roller, H, carrying the screen proper, J.

lhe screen is preferably composed of mosquito-netting or similar fabric;but it may be made of coarse muslin, wire-cloth, or any other suitablereticulated fabric, and is wound onto the roller after the manner of anordinary window-shade.

Secured to the lower or free end of the screen there is a bar, K,provided at its center with a catch, f, adapted to engage the loopSerial No. 206,906. (No model.)

cure the shade when it is pulled down to its fullest extent.- Aspring-catch, N, is also attached to one end of the bar K, said catchbeing adapted to engage a series of notches, t, in one of the bars D,and thereby assist in securing the shade in any desired position whennot fully extended. Two or 1nore vertical slits, b, are made in each ofthe strips D, said slits being so disposed as to intersect the groove m,in which the screen works in the edge of the strip, thus formingspringing auxiliary strips d, adapted to exert friction on the screen,and also to secure it at any desired height when they are pressedagainst its edges, the catch N being merely auxiliary to said strips.Disposed opposite each of the slits b, and secured firmly to the strip Dback of the groove m by the screw 0", there is a horizontally-arrangedrigid arm, Q, provided near its outer end with the setscrew o, adaptedto engage the auxiliary strip d and force it into contact with thescreen, thereby clamping and securing it in a manner which will bereadily obvious without a more explicit description.

The object of the bar E is to prevent flies, dust, 820., from passinginto the room around the roller H above the strips D,.said bar extendingbelow said roller, as best seen in Fig. 2.

Having thus explained my invention, what I claim is I 1.. Ina'window-screen, the grooved strips D, provided with slits b, thespring-roller H,

screen J,adapted to be wound upon said roller, its edges extending intothe grooves in said strips, and means for clamping the members of thestrips opposite said slits'b upon the edges of the screen for holdingthe latter in position, substantially as described.

2. In a window-screen, the grooved. strips D, provided with slits b, thespring-roller H, screen J ,adapted to be wound upon said roller, itsedges extending into the grooves in said strips, and the arms Q, securedto the strips outside said slits and provided with thumbscrews in theirinner ends for clamping the members of the strips opposite said slits bupon the edges of the screen for holding the latter in position,substantially as described.

3. In a window-screen, the grooved strips D, provided with the slits b,the spring-roller 'H, screen J, adapted to be wound upon said.

roller, its edges extending into the grooves in said strips, the bar K,secured to the lower end of the screen, and the arms Q, secured to thestrips outside said slits and provided with thumb-screws ,in their innerends for clamping the members of the strips opposite said slits b uponthe edges of the screen for bolding the latter in position, incombination with the auxiliary catch N,'mounted upon said bar andadapted to engage notches in the edge of one of the strips D,substantially as described.

4. In a Window-screen, the grooved strips D, provided with the slits b,the spring-roller H, screen J, adapted to be Wound upon said roller, itsends-extending into the grooves in said strips, the bar K, secured tothe lower end of the screen, and the arms Q, secured to the stripsoutside said s1its,and provided with thumb-screws in their inner endsfor clamping the members of the strips opposite said 20 slits bupon theedges of the screen for holding the latter in position, in combinationwith the auxiliary catch N, mounted upon said bar and adapted to engagenotches in the edges of one of the strips D, and the hook shaped 25handle, also mounted upon said bar K, and adapted to engage a staple, z,in the sill, substantial] y as described.
